Description

  The present invention relates to a sealed letter obtained by folding a sheet, which can be spread on a flat surface after being opened, can transmit a large amount of information, and can be manufactured very easily and its manufacturing method.

  Conventionally, as a means for transmitting a large amount of information such as a guide letter or brochure, a method is generally used in which various advertising materials are enclosed and sealed in an envelope and mailed. However, recently, management of personal information and the like is important, and it is necessary to avoid, as much as possible, an accident in which a sealed letter containing information on another person different from the recipient is mistakenly sent. Also, on the shipping side, we would like to reduce the great expense associated with the work of enclosing and sealing a lot of individual information. Under such circumstances, for example, a sheet for folding and sealing as described in JP-A-2000-43456 has been proposed.

Japanese Patent Laid-Open No. 2000-43456

  Since the folding and sealing sheet described in the cited reference described above describes information in a one-to-one correspondence on a single sheet and completes the folding and sealing letter, there is no possibility that other people's information is accidentally mixed. Moreover, since it completes to a sealed letter by folding, there exists an advantage that the effort of an enclosed seal can also be saved. However, a protruding sealing side requiring special processing, an adhesive application for sealing, a cutting sewing machine processing for tearing off the sealing piece at the time of opening, a release agent coating processing for easily peeling the bonded portion, two sewing machines It requires complicated and time-consuming processing such as opening by eyes, and it is expensive despite the advantages described above.

  In view of the above problems, the folding and sealing sheet of the present invention writes information on a single sheet and completes the folding and sealing sheet. In order to provide a foldable seal that can be easily checked for information because it unfolds on a flat surface after opening, and can be stored very easily with respect to manufacturing.

In order to achieve the above object, in the case of the fold seal according to the present invention, a set of unit sheets consisting of a plurality of leaf pieces transversely connected via a longitudinal fold line is longitudinal via a lateral fold line. After folding the two sets of concatenated letter sheets from the longitudinal fold line, finally, the fold seal sheet is folded in two from the lateral fold line;
The seal around the edge around 4 of the above-mentioned folding seal is a seal by folding the folding line in the horizontal direction at the lower edge, and in the longitudinal edges on the left and right, it is pseudo It is characterized in that it is formed by sealing by releasable adhesion of the adhesive film sheet, and sealing by releasable adhesion of the pseudo adhesive film sheet protruding from the edge of the leaf at the upper edge.

  In addition, since the lower side of the folded seal of the present invention finally becomes a fold line portion (folded portion) when the entire sealed sheet is largely folded in two, it is automatically sealed. The other sides are sealed by being releasably adhered by a pseudo adhesive film sheet coated on the facing pseudo adhesion planned surface in the case of the above-mentioned two fold.

  As the paper material used for the sealed sheet of the present invention, for example, usual paper such as high quality paper, matte paper, coated paper, synthetic paper, non-woven fabric, resin film sheet and the like can be suitably used. A pseudo adhesive film sheet used for pseudo adhesion for releasably bonding the folded opposite surfaces is, for example, a known heat sensitive adhesive layer on one surface of a substrate made of polyethylene terephthalate, biaxially oriented polypropylene or the like. It is possible to preferably use one corresponding to a thermal laminating method in which a pseudo adhesive layer is formed on the other surface while forming. This product adheres unremovably to the surface of the printed matter through the heat-sensitive adhesive layer, and is then folded and pressed so that the pseudo adhesive layer faces each other, and the opposing surfaces are releasably adhered by heat and pressure treatment. Do.

  In addition, although the folding seal of the present invention is completed by folding a sheet of sealing sheet lengthwise and crosswise, the folding means such as perforations or creases formed in the folding line is in the process of manufacturing the folding seal. It takes place in Therefore, if perforations are formed before the covering of the pseudo adhesive film sheet, perforations are formed only in the sealed sheet, but if it is formed after the covering, it will be formed in both. In the present invention, any case may be used.

  The fold seal of the present invention is folded from the longitudinal fold line at first, and then folded in half from the transverse fold line into two groups of leaflets, for example, three long sizes or mail service mainly of A4 size Finish the seal. Then, in the case of folding from the folding line in the lateral direction, the opposing surfaces of the opposing pieces are opposed in a peelable manner. Doing so will seal the entire perimeter of the sealed letter

  Since the folding seal of the present invention is finally folded from the lateral folding line, the lower edge formed by the lateral folding line is closed like a bag and sealed. Although the above-mentioned closed side is expressed as the lower edge in the embodiment etc., the upper edge may be closed in a bag shape by the design of the finally produced fold seal. When designed in the landscape orientation, either the left or right edge is a closed bag-like edge.

Since the folding seal of the present invention describes all the information in one sheet and finishes it into a folding seal, it mis-seals other's information which occurs when collecting and sealing a plurality of separate paper pieces printed with personal information There are no serious accidents such as
In addition, since a troublesome sealing operation can be easily performed only by covering the sealing sheet with the pseudo adhesive film sheet at the time of manufacture, even a layman can manufacture a large number of folded sealed letters in a short time. Of course, even if the operation is performed by a separate dedicated machine, the fold seal can be manufactured extremely easily with a machine having a simple configuration.

[4-fold letter F1]
The four-fold sealed document F1 of the first embodiment shown in FIGS. 1 (A) and 1 (B) is made of, for example, a sealed sheet S1 shown in FIGS. 3 (A) and 3 (B). In the sealed sheet S1, the first leaf 1 and the second leaf 2 connected in the lateral direction by the longitudinal fold line 5 are similarly connected in the lateral direction with the third fold 3 and the fourth leaf. The first leaf 1 and the third leaf 3 and the second leaf 2 and the fourth leaf 4 are vertically connected so as to be adjacent to each other via the leaf 4 and the transverse fold line 6.

  The surface of the sealed sheet S1 is covered with a pseudo adhesive film sheet G except for the right side portions of the second and fourth pieces 2 and 4 as shown in FIG. 3 (A). In addition, the said pseudo | simulation adhesive film sheet G is coat | covered in the state which protruded from the upper-and-lower-edges of 2 pieces. Moreover, as shown to FIG. 3 (B), the pseudo-adhesive film sheet G is coat | covering the substantially whole surface of the 1st leaf 1 and the 3rd leaf 3 on the back surface of sheet | seat S1 for sealing. And the said pseudo | simulation adhesive film sheet G is also coat | covered in the state which protruded from the upper-and-lower-edges of 4 pieces like the covering sheet S1 surface as stated above.

  A folding means such as a folding sewing machine or a folding line may be formed on the longitudinal folding lines 5 and the lateral folding lines 6, and the sheet may be accurately folded. In the first embodiment, a folding sewing machine is formed on all the folding lines. Further, the forming of the folding means such as a folding sewing machine may be performed only on the sheet forming the sealed sheet S1, or may be performed together with the pseudo adhesive film sheet G. In the first embodiment, a folding sewing machine is formed in both. This point is the same in the following embodiments.

  As shown in FIGS. 4 (A), (B) and (C), the letter sheet S1 having the above-described configuration is configured such that the back surface of the first leaf 1 and the back surface of the second leaf 2 face each other. It folds from the fold line 5 of the longitudinal direction, respectively so that the back surface of the leaf piece 3 and the back surface of the 4th leaf piece 4 may face each other.

  Then, next, the folding line 6 in the lateral direction is folded in two so that the surface of the second piece 2 and the surface of the fourth piece 4 face each other, and the sheet is folded into the state shown in FIG.

  The sealed adhesive sheet S1 folded as described above can be peeled off from the pseudo adhesive film sheet G interposed between the opposing surfaces of the leaves by pressing or heating / pressurizing with a press roller or a heat roller. By adhering to the seal, and sealing the periphery of the seal, the state shown in FIGS. 1A and 1B, that is, the four-fold seal F1 is obtained.

  The four-folded letter F1 manufactured in this manner is stacked in order of the first leaf 1, the second leaf 2, the fourth leaf 4 and the third leaf 3, as shown in FIG. 2 (A). The left longitudinal edge of the folded letter F1 is sealed with a pseudo adhesive film sheet G interposed between the facing surfaces of the protruding first leaf 1 and third leaf 3, and the right longitudinal edge is the second leaf It is sealed by the pseudo adhesive film sheet G interposed between the facing surfaces of the second and fourth pieces 4. Further, as shown in FIG. 2 (B), the lower side is sealed by the binding state by folding of the folding line 6, and the upper side is sealed by the protruding pseudo adhesive film sheet G, and thus folded in four. The circumference of the letter F1 is sealed.

  The recipient of this four-fold sealed document F1 is, for example, a display of a cutting sewing machine or a hook described along the upper edge of the surface of the first leaf 1 shown in FIGS. 1 (A) and (B), or Open the cut-off sewing machine with a cutting tool such as a scissors or a cutter according to the words of "Please open." Then, according to the design consisting of triangular halftone dots described in the upper right corner and the "open" instruction described therein, as shown in FIG. 2A, the right side of the four-fold sealed document F1 Opening is started with the non-adhesion area which is formed along the direction edge and not covered with the pseudo-adhesive film sheet G being a mark of peeling. Then, when the four-fold sealed document F1 is subsequently peeled off, all the other edges are sealed by the peelable pseudo adhesive film sheet G, so the original sealed document shown in FIGS. 3 (A) and (B) is finally obtained. The sheet S1 can be developed in a flat state (however, the pseudo adhesive film sheet G which has initially been protruded from the sealed sheet S1 is in a cut-off state due to the cutting at the time of opening). Then, various information hidden inside can be confirmed through the transparent or translucent pseudo adhesive film sheet G.

  As will be described in detail in the last embodiment, for example, a cutting line is indicated by a broken line along the lower edge, and a mark or a phrase such as "Please cut off from here." The connection sheet of the first leaf 1 and the second leaf 2 and the connection sheet of the third leaf 3 and the fourth leaf 4 may be separated by cutting the cut line with a known cutting tool such as scissors. . This point is the same in the following embodiments.

  In the above case, a cutting sewing machine is formed on the corresponding portions corresponding to and in line with the cutting lines of each leaf piece so that they can be easily broken at once, so that they can be broken manually and removed without using a cutting tool. I do not care. Further, a tear-off sewing machine for opening is formed at the folding line 6 in the lateral direction shown in FIG. 2 (B), and the folding line 6 in the lateral direction is broken by hand to release the binding state. It does not matter. In the case of forming a tearing sewing machine for opening at the folding line 6 in the lateral direction, it is extremely convenient that no cut pieces remain as chips after opening. This point is the same in the following embodiments.

[Six-fold letter F2]
The six-fold sealed document F2 of the second embodiment shown in FIGS. 5 (A) and 5 (B) is made of, for example, a sealed sheet S2 shown in FIGS. 7 (A) and 7 (B).

The folding line 17 is folded into the state shown in FIGS. 9 (A), (B) and (C).

  Then, from the folding line 19 in the lateral direction so that the second leaflet 12 surface and the fifth leaflet 15 surface face each other, the sealed sheet S2 folded in the state of FIG. 9 (A), (B) and (C). Fold in half and fold it into the state shown in FIG. 6 (A).

  The sealed adhesive sheet S2, which has been folded as described above, can be peeled off from the pseudo adhesive film sheet G interposed between the opposing surfaces of the leaves by pressing or heating / pressurizing with a press roller or a heat roller. By adhering to the above, and sealing the periphery of the sealed letter, the state shown in FIGS. 5A and 5B, that is, the six-folded postcard F2 is obtained.

  As shown in FIG. 6A, the six-fold sealed document F2 manufactured in this manner has the first leaf 11, the third leaf 13, the second leaf 12, the fifth leaf 15, the sixth leaf 16, and the first from the top The four leaflets 14 are stacked in order. The left longitudinal edge of the folded seal F2 is sealed with a pseudo adhesive film sheet G interposed between the facing surfaces of the protruding first leaf 11 and the fourth leaf 14, and the right longitudinal edge is the second leaf 12 And the pseudo adhesive film sheet G interposed between the facing surfaces of the fifth leaf piece 15. Further, as shown in FIG. 6B, the lower side is sealed by the binding at the folding line 19 and the upper side is sealed by the protruding pseudo adhesive film sheet G, and thus the six folds are made as described above. The circumference of the letter F2 is sealed.

  The recipient of this six-fold sealed letter F2 is, for example, a display of a cutting sewing machine or a hook described along the upper edge of the surface of the first leaf 11 shown in FIGS. 5 (A) and 5 (B), or Open it with a scissors, cutter, etc. according to the wording. Then, according to the design consisting of triangular halftone dots described in the upper right corner and the "open" instruction described therein, as shown in FIG. 6A, the right side of the six-fold sealed document F2 Opening is started with the non-adhesion area which is formed along the direction edge and not covered with the pseudo-adhesive film sheet G being a mark of peeling. Then, when the 6-fold sealed letter F2 is subsequently peeled off, all the other edges are sealed by the peelable pseudo adhesive film sheet G, so the original sealed letter shown in FIGS. 7A and 7B is finally obtained. The sheet S2 can be developed in a flat state (however, the pseudo adhesive film sheet G which has originally been protruded from the sealed sheet S2 is in a cut-off state due to the cutting at the time of opening). Then, various information hidden inside can be confirmed through the transparent or translucent pseudo adhesive film sheet G.

  In addition, a cutting line and marks and words for promoting various cuttings are described along the lower side edge, and the lower side edge is removed by a known cutting tool to obtain the first leaf 11, the second leaf 12 and the third leaf 13 The connecting sheet of the fourth leaf 14, the fifth leaf 15 and the sixth leaf 16 can be separated in the same manner as in the first embodiment, and the same as in the following examples.

  Furthermore, the cutting line can be broken at once, and it can be broken by hand without using a cutting tool, or a cutting sewing machine for opening can be formed at the folding line 19 in the lateral direction. It is also the same in the following embodiments that various opening means can be applied such that the cut pieces do not remain as chips after opening.

  In the first embodiment, all opposing surfaces are releasably adhered via the pseudo adhesive film sheet G. However, in the second embodiment, the minimum is necessary to seal the peripheral edge of the six-fold sealed document F2. The pseudo adhesive film sheet G is designed to be interposed between the facing surfaces. The same applies to the following embodiments in this regard, and both are designed to seal each edge of the folded seal with a minimum amount of facing surfaces and a minimum amount of pseudo bonding planned surfaces.

[Manufacturing method of 8-fold sealed letter F3]
The eight-fold sealed letter F3 of the third embodiment shown in FIGS. 10 (A) and (B) and FIGS. 11 (A) and 11 (B) is produced from, for example, the sealed sheet S3 shown in FIGS. 12 (A) and 12 (B).

The sheet is folded from the folding line 47 to the state shown in FIGS. 19 (A), (B) and (C).

  Then, the sealed sheet S4 folded in the state of FIGS. 19 (A), (B) and (C) is folded in the lateral direction so that the surface of the second leaf 42 and the surface of the fifth leaf 45 face each other. It is folded in half from 49 and folded into the state shown in FIG.

  The sealed adhesive sheet S4, which has been folded as described above, can be peeled off from the pseudo adhesive film sheet G interposed between the opposing surfaces of the leaves by pressing or heating / pressurizing with a press roller or a heat roller. By adhering to the above, and sealing the periphery of the sealed letter, the state shown in FIGS. 15 (A) and (B), that is, the six-folded postcard F4 is obtained.

  As shown in FIG. 16A, the six-fold sealed document F4 manufactured in this manner has the first leaf 41, the third leaf 43, the second leaf 42, the fifth leaf 45, the sixth leaf 46, and the fourth from above, as shown in FIG. The four-leaf pieces 44 are stacked in order. Then, the left longitudinal edge of the folded seal F4 is sealed with a pseudo adhesive film sheet G interposed between the facing surfaces of the protruding first leaf 41 and the fourth leaf 44, and the right longitudinal edge is the second leaf 42 and the fourth It is sealed by a pseudo adhesive film sheet G interposed between the facing surfaces of the five-leaf piece 45. Further, as shown in FIG. 16B, the lower side is sealed by the binding of the folding line 49 and the upper side is sealed by the protruding pseudo adhesive film sheet G. Thus, the periphery of the six-fold sealed document F4 is sealed.

  The recipient of this six-fold sealed letter F4 is, for example, a display of a cut-out sewing machine or a hook described along the upper edge of the surface of the first leaf 41 shown in FIG. In accordance with the wording, cut off with a cutting tool such as scissors or a cutter. Then, according to the design consisting of triangular halftone dots described in the upper right corner and the instruction of "open" described therein, as shown in FIG. 16A, the right side of the six-fold sealed document F4 Opening is started with the non-adhesion area which is formed along the direction edge and not covered with the pseudo-adhesive film sheet G being a mark of peeling. Then, when the six-fold sealed document F4 is subsequently peeled off, all the other edges are sealed by the peelable pseudo adhesive film sheet G, so the original sealed document shown in FIGS. 17 (A) and (B) is finally obtained. The sheet S4 can be developed in a flat state (however, the pseudo adhesive film sheet G which has originally been protruded from the sealed sheet S4 is in a cut-off state due to the cutting at the time of opening). Then, various information hidden inside can be confirmed through the transparent or translucent pseudo adhesive film sheet G.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, a total of four-leaf sealed sheets in which two leaflets are arranged at the top and bottom, a total of six-leaf sealed sheets in which three leaflets are arranged, or a total of eight-leaf sealed sheets in which four leaflets are arranged vertically However, it is also possible to use a sealed sheet composed of a total of 10 leaves or more pieces in which 5 pieces of upper and lower pieces are arranged.
Further, the form of the folding of the sealed sheet is not limited to the folding form of the embodiment, and may be bellows folding, winding folding, double folding, mixed folding thereof, or the like.
Further, there is no particular limitation on the width and height of each leaf, and it may be freely selected.
Furthermore, although the upper side edge which pseudo-adhesive film sheet G overflowed is cut and opened at the time of opening, it may be designed so that the lower side edge may be cut off and opened. In this case, the unit sheets connected vertically at the fold lines in the lateral direction are separated into two sheets. In addition, if the upper and lower edges are cut off, the film sheet that has run out disappears, so that it can be developed in a finally clean state.

The manufacturing method of the folded sealed document of the present invention is manufactured by adding the following steps to a long sheet or sheet-like sheet on which a sealed sheet is printed.
1) A covering step of covering a pseudo-adhesive film sheet G on a long sheet or sheet-like sheet on which a folded and sealed sheet is printed.
2) A folding step of folding a long sheet or sheet-like sheet in which the pseudo adhesive film sheet G is coated at a predetermined position.
3) A step of cutting out the folded long sheet or sheet-like sheet into individual folded sealed sheets S.
4) A bonding step of subjecting the cut folded sealed sheet S to pressure treatment or heating / pressure treatment to complete pseudo adhesion.
In addition, the said manufacturing process is an example, and the order of each process may be interchanged. In addition, a folding means such as a folding machine or a folding line may be disposed between any of the steps, and when cutting out separately, the margin in the flow direction is cut away with a slitter and then the top and bottom direction is die cut roller or guillotine method. It may be executed in stages, such as cutting with a cutting machine.
Furthermore, long sheets or sheet-like sheets coated with various film sheets may be cut out individually, and then may be finally folded after passing through the folding process. The order of the steps and the arrangement of the additional folding means forming step are manufactured in the step of arrangement suitable for handling the long sheet or sheet-like sheet.
